@filiz thanks
I will try this ratio and compare it to the one Ketchito said -
@ketchito thanks
-
@ketchito pH is between 5-5.5
The ratio of each preservative in blends we make is the same as preservatives from reputable companies like Inolex wich is broad spectrum. This way it cost much less than if we purchase the pre blend.
-
@ketchito thanks
Appreciated
I like to find files and comparisons like this. Where can i find more? -
@ketchito my preservatives are Ethyl Lauroyl Arginate HCl, glyceryl caprylate, caprylyl glycol, caprylhydroxamic acid
-
Thank you all
-
@ketchito do all amphoteric surfactant interact this way with anionic surfactants or just CAPB?
What would be a good ratio between anionic/amphoteric surfactant for best detergency, mildness and foam?
-
@zetein in my experience CAPB can’t clean clean the scalp and hair for for adult oily scalp. Even at %10, %15, %20 active surfactant. I don’t know how it works for majority of people
-
@Perry thanks a lot
-
@ketchito that was informative. I thought CAPB and APG would be milder than SLES but it looks they aren’t.
Which APG is mildest in your opinion?
-
@Perry i couldn’t open this cir table.
Decyl glucoside may be the cause, I don’t like it either but in new formula we are just using a small amount because of glyceryl oleate. -
@Perry so this stringiness of Shampoo doesn’t have an effect on hair and scalp?
Does increasing the salt reduce stringiness?
If yes, is it the more salt the less stringiness or it is something like salt curve? -
@Perry if you smell the salt from very close it has a weak but unique smell. Although these Shampoos don’t have salt, they smell like they have a lot of salt when you put them on scalp.
About orange essential oil degrading, what would be the problem? (This batch of oil, this supplier of oil or this oil and we should try another essential oil?)
-
@zacchaeus i am currently making faces wash with SLES and CAPB.
What about pH of Shampoo bar? Does it need to be high too?
-
@Perry here it says “Nitrosamines may be formed in cosmetic and personal care products only if they contain both an ingredient that acts as a Nitrosating agent and an amine ingredient”.
What is Nitrosating agent?
Does it mean all amines( cocamide DEA, MEA, MIPA, Methyl MEA) or some of them specifically?
-
@chemicalmatt if MEA is the the problem then why cocamide DEA is banned and everyone is seeking alternative for it instead of cocamide MEA?
-
@Perry thanks
-
@Farrukh i am from Afghanistan.
And you? -
@ngarayeva001 for me betaine even at %15 active doesn’t clean hair enough so there may not be much different between quantity of betaine and SCI
-
@chemicalmatt thanks
-
@Pharma for what reasons you prefer xylitol over sorbitol?
-
@Pharma what is ky gel?
-
@Pharma thanks
Can you name some good wetting agents and some ingredients to increase spreading and penetration -
@Zara do you know how to use HEC?
It is water soluble and can mix very easily buy after mixing you have to increase the pH to 8-10 for it to get thickened. And then you can decrease the pH back.
Decyl glucoside is very hard to thicken and you would need more HEC. Lauryl and coco Glucoside is not so difficult.
